Toshiba Libretto
The Libretto was a line of subnotebook computers designed and produced by Toshiba. The line was distinguished by its combination of functionality and small size, squeezing a full Windows PC into a device the size of a paperback book. The first Libretto model, the Libretto 20, was released on April 17, 1996, with a volume of and weighing just, making it by far, the world's smallest commercially available Windows PC at the time, and a trend the Libretto Range continued for many years. The original Libretto line was discontinued in Europe and the U.S. in 1999, but the production continued in Japan with the SS, FF and then the L series until 2002. The first L series Libretto was released on 18 May 2001 and the last just 11 Months later on 24 April 2002. Production of all Librettos ceased from 2002 until the release of the Libretto U100 in 2005.
It was a further five years before the Libretto returned again in 2010 with the limited-edition dual touch screen tablet W100 model.
Models
There have been many different models. The first Libretto models, the L20 & L30 used 486 processors from Advanced Micro Devices and were only available in Japan. Beginning with the Libretto 50, Toshiba used the Intel Pentium and later Pentium MMX processors. With the introduction of the L series in 2001, a move was made to the Transmeta Crusoe processor. The U100 of 2005 saw a return to Intel with the use of the Pentium M processor.The following models were available:

In 2001, Toshiba released the L series range of Librettos. This was the first major change of footprint since the range was first introduced and represented a significant improvement in performance over the previous models, however it also represented a significant increase in overall size. The L series had moved the Libretto range away from what was a UMPC, to that of an early Netbook.
The L1 had built-in USB and IEEE1394 Firewire. The L2 dropped the IEEE1394 in favor of an Ethernet port. The L5 was optionally available with built-in Wifi 802.11b. All models featured a widescreen display with the unusual resolution of 1280×600 pixels.
Like the majority of Librettos models produced, the L series were not officially available outside Japan.
